EXTENSION TABLE.

Application led January 3, L17922. Serial No. 526,554.

To all 'whom t may concern:

Be it known that I, CHARLES F. DanonscrrMIDT, a citizen `of the United States, residing at the city of St. Louis and State of Missouri, have invented a new and `useful Extension Table, of which the following is a specification.

This invention relates to improvements in extension tables, and consists in the novel construction hereinafter disclosed.

An object of the invention is to provide an extension table having a permanent nonextendible support, an extendible topy mounted to slide on said support and including anti-friction devices between the support and the sections of the top, and means for locking the sections of the top in predetermined extended position, together with means for supporting the insertible leaves below the top ofthe table.

Additional structural features and advantages will be apparent without further detailed mention thereof, from the following description taken in connection with the accompanying drawing, in which- Fig. 1 is a plan view of the table showing the substructure in dotted lines.

Fig. 2 is a side elevation.

Fig. 3 is a vertical section the line 3-3 of Fig. 1.

Fig. 4 is an end elevation, a portion of the structure being broken away.

Fig. 5 is a plan view with moved.

Fig. 6 is an inverted plan view of one seotion of the table top.

The table support may be constructed in any desired manner. In the form illustrated in the drawing the permanent support of the table includes legs 1 upon which is mounted a frame comprising side members 2, transverse end members 3 and depending vertically disposed side members 4 extending at right angles to the under faces of the members 2. .This structure forms a rigid frame or pedestal for supporting the extendible sections 5 comprising the table top. The members 2 have longitudinal channels or grooves 6 in the upper faces thereof and the sections of the top have depending longitudinal strips 7 secured thereto, a portion of each of the strips 7 being cut away to form a channel 8 to receive the inner edges of the members 2.

The sections 5 are supported by the mem'- hers 2 in such a manner that they maybe substantially on the top removed longitudinally thereon and, in order to provide for easy movement of the sections of the top, antifriction devices in the form of hemispherical metallic members 9 are mounted in the grooves 6 adjacent to the outer ends thereof, and similar members 10 are mounted on the under faces'of the sections 5 of the table top near the inner end of each of said sections and in staggered relation in respect of the members 9, so that each section 5 rides upon the members 9 and 10, thereby preventing the sticking of the sections of the top when they are moved on their supports.

Locking devices are provided on each section of the top so that the longitudinal movement of the top sections may be limited to provide a4 proper interval between the adjacent ends of the sections for the insertion lof the supplemental leaves of the top of the table. These'locking devices comprise pivoted levers 11 one of which is hinged to each of the sections 5 of the table top by hinged construction 12 mounted adjacent to the inner ends of the sections and upon the under face thereof. The levers 11 eX- tend respectively through notches 13 formed in the upper edges of the transverse members 3, the ends of the levers 11 being downturned to formy handles 14, one of which handles is adjacent to the outer edge of each of the table top sections 5 so that it may be readily engaged by the operator and raised, permitting movement of the sections 5. The under faces of each of the levers 11 is provided with a series of notches 15 arranged at intervals so as to lock the sections of the table top against outward longitudinal movement when a proper interval between the adjacent edges of the sections of the table top is provided for the reception of the supplemental leaves of the table. Obviously, therefore, the sections of the table top may be freely moved when the levers 11 are raised by engagement of the handle sections 14 thereof. When releasing the handle sections the lever will drop lby gravity, the shoulders of the notches 15 engaging against the bottom wall of the notches 13 in the end members, thereby preventing further outward movement of said sections of the top.

It will be noted that each of the levers 11 has a transverse pin 16 therein adjacent to the hinge 12, so that when the sections of the table top are moved outwardly to the limit of their movement, the pin 16 will contact with the end members 3 at the sides of the notches 13 preventing the sections from being removed from the permanent support by the longitudinal movement of said sections.

In order to provide a convenient support for the supplemental leaves 17 for the tablev when they are not in use, a series of transverse slats 18 extend between the members 4f in a plane subjacent to the plane of the tab-le top. Thus provision is made for storage of the supplemental leaves in a convenient position so that they may be readily inserted. when it is desired to extend the table.

I am aware that the invention may be modiiied in certain particulars without departing from the spirit and scope thereof.

I do not limit myself to the exact details of construction and arrangement shown, but what I claim and desire to secure by Letters Patent, is Y l. An extension table, comprising a supporting frame the parts of which are relatively Xed and having a pair of parallel grooves in the upper side thereof one near each side of the frame, bearing elements secured in said grooves near the outer ends thereof, top sections resting on said bearing elements and arranged to contact at'their inner edges to form a table top and being movable outwardly in opposite directions, bearing elements secured to the under sides of said top sections near their inner edges and arranged to bear upon the bottom walls of said grooves and cooperate with the {irstnamed bearing elements to support said sections, and L-shaped members secured to each of said top sections and engaging under the inner edges of the upper portions of said frame.

2. .In an extension table, a frame comprising two parallel continuous side members having grooves in Vtheir upper sides, and two end members rigidly connected with the side members; a bearing element secured near each end of eachV of said grooves; top sections arranged to operate upon said bearing elements; bearing elements secured to the under sidescfsaid top sections near their inner edges and arranged to bear upon the bottomrwalls of said grooves to cooperate with the first-named bearing elements in supporting the top sections; L-shaped members secured to said -top sections and engaging under the inner edges of said side members; and pivoted latches supported byvsaid sections and arranged to engage with said end members to holdfsaid sections together or in dierent spaced positions as desired.

3. An extension table comprising T-shaped relatively rigid and continuous side frame members each having alon'gitudinal groove in the upper side thereof, two end members rigidly connecting the ends of the vertical portions of said side members, bearing elements secured in said grooves near the outer ends thereoLtop sections resting on said bearing elements andY arranged to contact at their'inner edges to form a table top and being movable outwardly in opposite directions, bearing elements secured to the under sides of said top sections and arranged to bear upon the bottom walls of said grooves to cooperate with the iirst-namedbearing elements to supportsaidIsections, L-shaped members secured to each of said top sections and engaging under the horizontal portions oi said T-shaped frame members, and latch devices `supported vbyl said top sections and engaging said end members to hold said sections together or in different spaced positions as desired.
